Antifungal peptides from the marine gorgonian-associated fungus Aspergillus sp. SCSIO41501.
2021
Abstract Three undescribed cyclic lipopeptides maribasins C-E and four undescribed linear peptides aspergillipeptides H–K together with three known analogous maribasins A-B and marihysin A were isolated from the marine gorgonian-associated fungus Aspergillus sp. SCSIO 41501 (Trichocomaceae). Their structures were determined by spectroscopic analysis, and their absolute configurations were further confirmed by Marfey's methods. Maribasins C-E and maribasins A-B showed significant antifungal activity against five phytopathogenic fungal strains with MIC values of 3.12–50 μg/disc. Structure-bioactivity relationship exhibited that the β-amino fatty acid chain could significantly affect the antifungal activity of this type of cyclic lipopeptides.
